UPDATE 3-Air Force agrees to brief Boeing on tanker loss

(Recasts with Air Force briefing, adds Teamsters)

WASHINGTON, March 4 (Reuters) - Under mounting pressure from lawmakers and a top Pentagon leader, the Air Force on Tuesday agreed to speed up a briefing with Boeing Co (BA.N: Quote, Profile, Research, Stock Buzz) about why it lost a $35 billion aircraft contract to Northrop Grumman Corp (NOC.N: Quote, Profile, Research, Stock Buzz) and its European partner EADS (EAD.PA: Quote, Profile, Research, Stock Buzz).

Tight-lipped since it got the bad news on Friday, Boeing on Tuesday demanded immediate answers, calling the Air Force's plan to delay the briefing about the lucrative contract until March 12 inconsistent with procurement practices.

Sen. Patty Murray and Rep. Norman Dicks, both Democrats from Washington state, said the meeting would now be slated for Thursday, and would help Boeing decide whether to protest the contract award, which has sparked a political firestorm.

Pentagon acquisition chief John Young defended the contract award, saying the Air Force followed the rules carefully and there was no obvious reason for a protest in this case. He said an independent Pentagon team of civilian and military experts also tracked every step of the process, just to be sure.

Young said he had also urged the Air Force to brief Boeing "as soon as possible," possibly on Thursday, and there was no reason for an extended delay.

Despite the outcry on Capitol Hill about the potential for U.S. job losses, Young said federal law did not allow the Pentagon to consider how many jobs were created by a weapons program and required it to get the "best value" deal it could.

"I don't think anybody wants to run the department as a jobs program," Young said, noting he was usually under pressure from lawmakers to reduce the cost of weapons programs -- not maintain jobs in a certain region.
